If Rogue's first instinct was to hide, Steve's was to protect. He reached forward, wrapping his arms around her and pulling her against his chest, resting his head on top of hers and enveloping her as completely as possible. "I'm sorry," he murmured; he didn't know what exactly had happened, but he knew he didn't want Rogue upset. "If you want to stop, that's fine. We don't have to do this, you know."
